Benefits of technology

"The present invention relates to a system and method for identifying a user of a handheld device. The device comprises a housing and a sensor system disposed along a periphery of the housing. The sensor system is responsive to a plurality of simultaneous points of contact between a user's hand and the device to generate observation signals indicative of the plurality of contact points between the user's hand and the device. The device further includes a user identification database storing data corresponding attributes of a plurality of known users, wherein the attributes of the plurality of known users are used to identify a user. The device is further comprised of a user identification module configured to receive the observation signals and identify the user based on the observation signals and the attributes of the plurality of known users. The invention allows for accurate identification of users through their unique physical attributes and finger movement patterns, enhancing the security and user experience of handheld devices."

Embodiment Construction

[0031]Example embodiments will now be described more fully with reference to the accompanying drawings.

[0032]A system and method for user identification is herein disclosed. The system combines one or more user identification techniques to authenticate and / or identify a user. The techniques may be passive techniques such as identifying a user by the way which the user grabs the handheld device, the trajectory that the device follows when the user picks up the remote, the user's first touch of the device, and the user's heartbeat. The techniques may also be semi-passive, such as having the user draw a shape, e.g. a circle, on a touch-sensitive surface of the handheld device. For simplicity, the techniques are first explained as applied to a remote control 12 that may be used with a television, a set-top box, a computer, an entertainment center or other host device. It will be apparent that the techniques are also applied to all handheld devices where user identification would benefit...

Abstract

A system and method for identifying a user of a handheld device is herein disclosed. The device implementing the method and system may attempt to identify a user based on signals that are incidental to a user's handling of the device. The signals are generated by a variety of sensors dispersed along the periphery or within the housing. The sensors range may include touch sensors, inertial sensors, acoustic sensors, pulse oximiters, and a touchpad. Based on the sensors and corresponding signals, identification information is generated. The identification information is used to identify the user of the handheld device. The handheld device may implement various statistical learning and data mining techniques to increase the robustness of the system. The device may also authenticate the user based on the user drawing a circle, or other shape.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 046,578, filed on Apr. 21, 2008, the entire disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates generally to method an system for identifying a user of a handheld device, e.g. remote control systems. Many systems would benefit from easy, non-intrusive user identifications. For reference only, many aspects of the invention and the background relating to the inventions are described in relation to a remote control system, suitable for control of consumer electronic products and home appliances, that includes a touch sensitive handheld remote control unit that detects holding and grabbing patterns of the user as well as other characteristics such as the trajectory at which the user raises the remote and first touches the remote to identify the user.[0003]Handheld remote control units, typically featuri...
